Hydraulics Characteristics of the Close Gap in Large-Scale Beach Reclamation Works in Radial Sandbanks

Abstract:

By the2-D tidal flow mathematical model, Calculation and analysis of hydraulics r Characteristics of the Longkou ine LV four port rcclamaiton project;and the relationship between the fill area and the width of of longkou. Research shows that, after the completion of an embankment, with the inning area fill, Longkou velocity gradually decreases. In I, II area harbor dam is formed, When the fill range from Longkou 1km ,and the Long kou width is reduced to 50m, I, II zone Longkou maximum velocity were 1.42m /s、1.54m / s, can meet the requirements of the closure gap.when III area harbor dam formed,if the fill maximum range from Longkou 1km, then closure-gap width at least to maintain 200m; for closure-gap width below 100m, then in the north and south area at the same time need to built bank. The ebb tide duration of the Longkou greater than the flood tidal duration;during the ebb tide, flow velocity basically stable, relatively small, Longkou closure should be selected during low tide and the low tide period.
